I was also healthy until I had a closed reduction for a broken wrist. It was right after that that I developed RSD. I have had constant health problems ever since. I believe that my RSD was caused by the horrific consequences of a botched closed reduction of my wrist, not from my lifestyle. I was also watching my weight and very active until I got RSD. Since then I have lived in constant excruciating pain and my life has never been the same.
P.S. I have had over 2 1/2 years of constant pain from my RSD that has never gone into remission. I have also had it spread to all of my limbs and stomach.
